A fitting 2nd book to this white-knuckled trilogy. Lark continues her journey to find her brother. She now has to deal with what her power actually is and what she can do. Luckily, she has help on the way to discovering both her own powers and the mystery of where Basil has gone. Still, my favorite character is Nix. He provides that R2-D2 comic relief and common sense. Although I’m still trying to wrap my head around the level of dystopia this trilogy contains, the world makes a little more sense in Lethe. A little. Maybe I’m not meant to fully understand until the 3rd novel. That seems to be where readers are led. I have always disliked reviewing second books in a series because I don’t want to give away anything from the first book in case someone hasn’t read it yet. So I’ll stop my review here by saying READ THIS SERIES!!!! If you like dystopian novels, books with a magic element, and/or survival novels, you will probably enjoy this book.
